IET Networks, Volume 15, Issue 1, January/December 2026.This paper proposes a reconfigurable intelligent surface‐based deep reinforcement learning MAC (RIS‐DRL‐MAC) protocol for terahertz mesh networks. By embedding RIS perception into the MAC decision loop and using a distributed TD3 algorithm, the proposed scheme achieves a cross‐layer optimisation of beam direction, access timing and RIS phase control ...

Trajectory Optimisation for UAV Data Collection in IoT‐Based WSN: A Lévy Flight‐Based Approach
IET Smart Cities, Volume 8, Issue 1, January/December 2026.In large‐scale IoT and WSN deployments, data transmission to base stations is often limited by restricted network coverage, and drones can help extend connectivity by collecting data from cluster head nodes. This work proposes an energy‐efficient drone‐assisted data collection approach that jointly optimises system costs and energy consumption, taking ...

Robust Adaptive Beamforming for Multiple Signals of Interest with Cycle Frequency Error
EURASIP Journal on Advances in Signal Processing, 2010 This paper deals with the problem of robust adaptive array beamforming by exploiting the signal cyclostationarity. Recently, a novel cyclostationarity-exploiting beamforming method has been proposed by J.-H. Lee and C.-C.
